You could have a detailled explanation of what is in the /proc directory in the linux man page

I am seeing a message on my taskbar <code> System updates are available </code> . When I am tapping to that message it is showing some 29 MB updates. I am running sort of internal memory, so every-time I am postponing the updates to <code> later </code> (I think it will consume 29 MB internal memory). Is this true that on installing the updates will consume internal memory? I am using HTC explorer having gingerbread(2.3) version of Android.
|
I think in many cases updates are to the system partition. The storage on your phone is split across different partitions, the system one is not where you download third party apps to and usually run out of space. So anything an update does on the system partition would not count against you, unless it repartitioned the storage to give system more room, which is rare and usually only heard of in bizarre cases where the device just couldn't support a newer version of Android any other way. Please make sure you have gone through the list of apps in your settings and moved any that you can to your SD card, by the way, if you have one. If your phone is rooted, there are other options as well, such as removing system apps that have been updated and are using space in the usual user partition for their update data, etc..

I know I could disable JavaScript in most Browsers. Is one able to disable it for WebViews also? I mean every App could specify its own WebView and is able to turn JavaScript on/off inside their app and they could inject JavaScript that infects my phone somehow. I'm aware that this WebView may lose its function or behave in an unexpected way. If it matters I have a Galaxy Nexus with JellyBean.
|
If the developer do not give you access to the (Web)Settings of the WebView, you will not be able to disable JavaScript in the WebView.

I want to know if I take the <code> mkfs.ext3 </code> file, or any other mkfs file, from another Linux system like Ubuntu, and put it with my <code> mkfs.vfat </code> and <code> mkfs.ext2 </code> located at <code> /system/xbin </code> , Would it work? And how can I call them from terminal emulator? If relevant, I have a Huawei u8160 running Cyanogenmod 7.2. EDIT: I realized that it cannot be taken from Ubuntu or any non-ARMv6 built system ,so my question now is: Where can I find binaries that are built for ARMv6 phone? (at least mkfs ones(except mkfs.vfat and mkfs.ext2,I already have them) ).
|
Native binaries (as the <code> mkfs.* </code> tools are) need to be compiled for the platform they should run on. So if you take the <code> mkfs.ext3 </code> from your Ubuntu workstation, which probably is either x86 or x86-64, it will not work on your Android device, which most likely uses ARM architecure.

I have two phones, the LG GT540 optimus and Samsung GT-i5800 , both using Android 2.1, and I intend to sell them in the near future. Before selling (just like before selling a HDD), I want to wipe all the personal DATA from the phones. Question: Does a "factory reset" (from the Android phones "menu") surely wipe all the personal data? Or will there be something left to use? (ex.: contact list, Gmail password, etc.?)
|
By doing a factory reset and formatting the SD cards, I would say that it is safe enough to sell. If you want to be perfectly sure, flashing the original ROM with option of wiping the cache will make the phone as good as you got it when you purchased. Of course, still you have to format the SD card in that case as well. To know how to flash the original ROM for you LG Optimus GT540, you can visit this page, which has a step by step instructions about this process. You should be able to find similar such page for your other Samsung device just with Google search. Update: I found this web page, which explains about to how to downgrade i5800 to 2.1. By that process you can get the original ROM (watch out for the region) and safely sell.

A recent update to CWM touted the ability to perform incremental backups instead of full ones. Having performed those for a while, I find that I have quite a few old backups that I don't know if I can remove, since newer backups may depend on them. Last time I was in this situation I deleted all of the backups and made one full clean backup. That, however, carries the risk of some failure before the new backup is complete. Is there any way to tell CWM to perform a full backup, so that I can safely remove all of the old ones?
|
Technically, CWM 6 isn't doing incremental or full backups. What it is doing is storing "blobs" that are shared between backups if the data hasn't changed between the two. When you run a new backup, it reuses what it can. If you delete a backup set, you don't actually delete the data, and the next time you run a backup, CWM deletes any blobs no longer in use.

Is it possible to flash a smartphone like the Samsung Galaxy SIII or an LG Optimus 4X with a vanilla Android ROM like the one that has been flashed on Galaxy Nexus or Motorola phones (I think)? I am asking because manufacturers like Samsung, LG, HTC tend to make ROMs for their smartphones and tablets with preinstalled launchers like Touchwiz or HTC Sense. They explain their decision by saying that they want to make their devices to look unique against their rival devices. The problem is that Android updates for their phones and tablets get delayed and there are incidents in which some devices - which are more than capable of running the upcoming version of Android - fall way behind or never get updated at all. So, what I am basically asking here is if there is a way to install vanilla Android, excluding CyanogenMod or any other modified vanilla ROMs, on an Android based smartphone?
|
Well Google only develops "vanilla" Android (called AOSP for Android Open Source Project ) for some selected phones (the Nexus Series). Manufacturers use this as base for their phone's OS. So you probably won't get a "vanilla" Rom from your manufactures, but there are probably a few AOSP-based Ports for your phone. (CyanogenMod is also based on AOSP) Rom-Developers tend to use an existing ROM like AOKP or Cyanogen as base because it's already compatible with a lot of devices. Porting "vanilla" AOSP is quite difficult and time-consuming because it lack's drivers and phone-specific code.

I see there is a Power Saving switch in the Galaxy S3 . What makes the Galaxy S3 save power when it is turned on? Is there a difference this and using JuiceDefender ? Can using JuiceDefender and turning on the Power Saving switch help or hinder performance?
|
Well, Samsung's Power Saving Mode consists of 4 features: CPU Power Saving : Limits the Maximum Performance of the Processor (May also disable some cores) Screen Power Saving : Uses a low power level for the Screen Background Color : Uses a dark Background Color for some apps, which might reduce Power Consumption on some Screens(See stackexchange-url ("here")) Turn off haptic feedback : Is the vibrating if you use the Hardware keys or type something on the virtual keyboard. JuiceDefender consists of several other Features which might save some Battery, if correctly configured: It let's you control when to use WLAN/2G/3G connection, so you don't need to change them manually (It can be configured to disable all 3G and WLAN at night for example) It has location aware WLAN control, so it can automatically enable/disable WLAN when it's available in this location It can also do CPU-Scaling, limiting your CPU-Power when you're phone is in idle state *Some features might not work because they need a specific ROM So JuiceDefender can save a lot of battery life if properly configured and will only slow down you're phone when it's not in use (only if configured properly). (CPU) Power Saving will defineatly reduce your performance.

For rooted phones, there are several apps which require root privileges. Knowing this, the user does allow the app to get root. Now, the app would have been installed with a set of x permissions, say <code> INTERNET, LOCATION </code> . Now, on gaining root, is it possible for the app to secretly (or not) give itself extra permissions eg. <code> BLUETOOTH </code> ? I read somewhere that the Apps requiring <code> INTERNET </code> or <code> BLUETOOTH </code> permissions are added to a user group which has access to these device files. So, can a rooted app associate itself to that group and gain the permission ?
|
Yes, all rooted apps theoretically can use the entire system, including all facilities that otherwise need app permissions. They could also modify the permissions database "under the radar" to grant its non-root part more permissions than were requested at install time. You have to trust root-using apps not to violate their given permissions.

A phone user manual (HTC Wildfire S. Android 2.2 ) says 'Home screen has seven panels that you can customise'. The system settings do not contain an option to modify the number of panels. I was searching for this on the web and was not able to find any solution that does not involve third-party applications. If this requires programming, please, move the question to StackOverflow and respond with detail.
|
If you don't want use 3rd party apps: This requires decent computer skills and a rooted phone , but here are the steps for android 2.3 Gingerbread. Copy /system/home.apk from your phone to pc. Decompile home.apk using apktool. Goto [decompiled folder]/res/values/integer.xml Change <code> <integer name="number_of_desktop_panes">5</integer> </code> , to 7 or whatever you want. Save it,and compile the apk using apktool. Copy it back to phone i.e to /system,change its permissions to -rw-r-r.

I see that there is a Star system but I really can't seem to figure out how to star a map in the application, or outside of it for that matter, it's driving me insane. How to I save an address in Google Navigate, from my Android device? Finally figured out how to do it in Chrome but I keep forgetting how. Not intuitive at all. In Google Chrome type in an address. Once the search results pop up click the blue link on the side bar. The little popup box will show up in the map blocking the view of the map. There is a star in there. Click it. (Red Circle in picture will help.) But still don't know how to do the same thing on the Android app?
|
If you are referring to the Google Maps Android application (aka maps), the star option is available from within the location details: Open the "maps" app; Search or navigate to the desired location; Tap over the balloon with the location name; After the location options page opens, you'll find on the top/right corner a star; Tap the star and that location is now starred by you. Access The Starred locations Navigation app In the Navigation app, swipe left to see your "Starred" locations. Tap the one you want to get your Navigation directions. Maps app Tap the top/left app icon, just before the search box and select "My Places".

There are many apps out there to limit data usage of entire system. Using Firewall, I can block an app from accessing Internet, too. But, I don't want these. I want to limit data usage of individual apps. e.g. - AppX should be firewalled if it comsumes 1GB within a day or month etc. How can I achieve this? I am rooted on ICS. I have tried to use Tasker but without luck.

I found this app " Onavo ". I did not try it but maybe you want to ;) I read that you can set the limit in the data usage settings. But i don't find the settings, maybe because I use stock rom. Hope this answer could help you.

Is it possible to persist the Background Process Limit setting? It's lost upon reboot and reverts to Standard Limit. Settings \ Developer Options \ Background process limit Android 4.0.3
|
Do not think its meant for persisting... See Dianne Hackborn's comment Also had a mosey around the ICS source code found in <code> packages/apps/Settings/src/com/android/settings/DevelopmentSettings.java </code> Source code to the related screen, found on Android's github. By looking for the variable that is associated with Settings > Developer Options > Background Process Limit (see line number 103 ) and (See line number 215 ) called <code> mAppProcessLimit </code> . With that in mind, keep looking further down in the source, the routine that is responsible for saving the settings for this particular screen called <code> onPreferenceTreeClick </code> . That is, in programming parlance, called a " listener " that is monitoring the changes made on that screen and writes it out immediately to the backing store by Android. (See between line numbers 790 and 858 ) Unfortunately, the " listener ", in this case, does not have a reference to the persisting/saving of the value for that variable <code> mAppProcessLimit </code> ; which is what the OP is experiencing, set it for the duration of when the handset is alive, then upon reboot, it gets lost. In short, you cannot do anything about this as that is built straight from the oven, and bundled onto your handset, but with that in mind, you can roll-your-own-custom ROM variant of ICS with a modified version of the source to do that.

I have forwarded machine port to emulator using following command adb forward tcp:1234 tcp:8080 I wanted to see currently what all ports are forwarded to avoid any conflicts. How to do that ?
|
Do you mean you want to see which ports are being used on the PC or Android device? You can use the <code> netstat </code> command for this. On Windows: <code> netstat -an | find /i "listening" </code> On Linux: `netstat -an | grep "LISTEN " (notice the space after LISTEN) This shows all the ports that are listening for incoming connection (i.e. have a server of some kind behind them). If you need to know which server, you can use this on Linux: <code> netstat -anp | grep "LISTEN " </code> . Don't know about the Windows counterpart, but there's a <code> -o </code> switch to print the process ID and you can compare it to the ones in task manager.

I have a micro-usb headphone (from my LG GS155 phone that is a feature phone). I plugged it to my Xperia Mini Pro (Android 4.0) but it did not work. Is Micro-USB headphone supported by Android? How does it should be configured to work?
|
The “Micro-USB” headphone used by LG GS155 is not really an USB device — it just uses the USB connector for the same analog audio signals as in usual 3.5 or 2.5 mm round connectors. Look at the MicroUSB to 3.5 or 2.5 jack headset pinout . In order to work with such headsets, the phone needs to have the appropriate hardware to detect the type of connected device and switch functions of USB port pins from USB to analog audio. It is highly unlikely that the phone will have such hardware if it also has a standard 3.5 or 2.5 mm audio connector. Even older HTC phones using the proprietary “ExtUSB” connector compatible with Mini-USB did not switch pin functions when a headset is connected — they used separate pins for audio . The only way to connect this headphone to your new phone is to build an adapter with a 3.5 mm plug and a Micro-USB Type B receptacle connector, so that the headphone will be connected to the audio circuit through the 3.5 mm audio connector on the phone.

I've just read about the chinese MIUI Phones ( Mi Two ), my question is wheter they work in Europe, or might there be some issues because of other phone networks? Might there be some other issues apart from that? Bonus Question: Does the official MIUI-Rom has any other languages than Chinese?

According to GSMArena, the Xiaomi Mi-Two supports the following frequencies: 2G Network: GSM 850 / 900 / 1800 / 1900 3G Network: HSDPA 850 / 1900 / 2100 You can check what frequencies your country uses here . It should work in most if not all EU countries though. Also, it supports Chinese and English officially but there is unofficial support for other languages, located here .

Lately I've been having trouble keeping a connection to Wi-Fi, first at home and now at work. What happens is that after a while I'll notice that my phone is using 3G. If I go into my Wi-Fi settings, I'll see a strong signal from my router. When I try to connect manually, I often get the message, "Failed to connect to network" with no further details. (There's a special place in hell for those who write error messages that give no indication of the nature of the problem.) Other times I can connect, but the signal is reported as weak and drops quickly. My computers can connect with no problems and report strong wireless signals. My roommates have no similar problems. I have a Galaxy Nexus running Jelly Bean. My roommates have a Galaxy Note and a Galaxy S2, respectively, both on ICS. What's wrong with my phone? Additional details My phone is rooted but running the stock ROM. My phone is the international GSM version. I first noticed this problem while using Tasker to stackexchange-url ("implement a Bluetooth wireless leash"). I've stopped using the leash--and Bluetooth entirely--but the problem persists. I'm still using Tasker for other things. In trying to track down this issue, I disabled "Avoid poor connections" but that change had no effect. I'm willing to consider flashing stuff to my phone as a last resort, but I strongly prefer alternative solutions. I didn't have problems initially, so I doubt the radio is to blame. Furthermore, I will down vote any answer that provides an incompatible ROM/radio, etc. or that provides it from a non-reputable source.
|
My solution, which seems to be working so far, is quite related to what was proposed by t0mm13b. That proposal was to adjust the DHCP settings. However, my router is quite limited in functionality and it's impossible to adjust wifi settings on it. Insane, I know. So, I set my phone to use a static IP address instead of using DHCP. So far, so good.

On my desktop computers, I use Firefox with the Firefox Sync service but on my mobile Android device I prefer using Chrome Mobile. Is there any way to sync Chrome Mobile with Firefox Sync? (I thought of syncing at least history, bookmarks and password). Comment : For now, I'll use XMarks and LastPass to synchronize my bookmarks/history (and passwords for Chrome Desktop only). But that's indeed not the ideal solution because I need a running Chrome to have the synchronization with my Chrome Mobile running. Because of this, I plan to write a small tool, that hooks into the web APIs of Firefox Sync and Chrome Sync to sync them against each other.
|
There's no direct relation between the Chrome Mobile and any Firefox version. What you can do, is to synchronize the information from your Chrome mobile to the Chrome desktop version, and then, using a desktop application, pass the bookmarks for any other browser. Xmarks is a FREE Bookmark Sync application that supports among others, synchronization between Google Chrome and Mozilla Firefox: Install Xmarks on each computer you use, and it seamlessly integrates with your web browser and keeps your bookmarks safely backed up and in sync. Xmarks will sync across browsers too. Today we support Firefox, Chrome, Internet Explorer, and Safari (Mac OS). Additionally, you can go Premium and benefit from the Android application to ease the process: Premium Features Overview Xmarks on Android The Xmarks mobile app for Android is available in the Google Play Store. You can also install via lastpass.com/xmarks.apk It lets Xmarks Premium users access all their desktop bookmarks and open tabs on their device.

I've noticed two days ago that I've initiated some random things while having hands in my pockets and phone was in as well... And today I just picked up a call and while talking on the phone I realised that I turned on stuff with my face... It seems that proximity sensor isn't working or working improperly. How do I test it without placing a call? How can I test proximity sensor anyway? Is it at all possible? I've read about some proximity sensor light... I don't see any light turning on or anything... I can just locate two holes behind glass between front camera and speaker. I suppose one of them (or both) is proximity sensor. Galaxy Nexus is 2 weeks old and running Jelly Bean
|
Install a sensor app like AndroSens or AndroSensor . They both are able to show you the proximity information. Note: The sensor only distinguishes between near and far proximity (0-5cm and > =5cm usually). It is OK that you won't get accurate distance measurements.

I have a text message sent from a phone number that is not yet linked in any other method. Is there a way to use this message's number to create a new contact or modify an existing one directly from the text messaging application? If it is relevant, I use Gmail for my contacts and have imported from Facebook. I have Android 4.0 (Ice Cream Sandwich). What I've tried stackexchange-url ("This question is vaguely similar"), but not quite what I'm looking for. I know I can copy/paste the number if I open the "modify recipients" dialog, click on the number, and click/hold to open the cut/copy/paste tool. I can also simply write down the number on paper. I'm looking for an alternative. There are no menu options if I select the message at the top-level of the Text app. The menu options while in the text message thread don't seem relevant: Insert smiley Delete Set priority Add subject Modify recipients The menu options if I click and hold on an individual message don't seem relevant: Delete message Forward message Copy message text Protect message View message details Add to task

The description of the app, Battery Calibration , claims that after changing ROMs you should recalibrate your battery gauge. It has good reviews so it seems like the general concept is sound and trying the app at least won't cause harm. What I'm wondering is what the battery statistics have to do with the ROM. My understanding is that the batterystats file contains a mapping of charge values in mV to %, so why does it need to be regenerated if a new ROM is flashed?
|
No. This App just removes the file "batterystats.bin" in the "data/system" directory. It has nothing to do with your battery life and also not the status indicator of your system. It only keeps the Infos in the "Battery Usage" screen. It will also be resetted every time you connect to a power source. Further Information and Sources: XDA-Developers and Dianne Hackborn (Google employee)

I just found this App ( Battery Repair ) on the Google Play Store, my question is how can it make my battery last longer. What optimazions are they doing? Has anyone tested this tool, does it work?
|
No app can "optimize" or "maintain" the battery in any way as it can't get the necessary access to the hardware -- probably not even if it required root. This app explicitly advertises that it does not. Anyway, the manufacturer's engineers surely have already implemented all the necessary optimizations. There is no way that the app's developers knows anything useful about every phone's charging circuitry and battery that the engineers don't. In short, there is no way this app does anything useful at all. (It might even be malware, but I don't get that impression in this case). (Note: the following is probably not true) The only thing an app can do (on a rooted phone) is to recalibrate the battery. If the battery is miscalibrated the OS might think that it is as good as empty and force a shutdown although there is still a useful amount of charge left. One app that does this is the aptly named Battery Calibration .

Apparently any GPS module made in the US and exported is classified as a munition if it is: Capable of providing navigation information under the following operational condition: At speeds in excess of 515 m/sec (1,000 nautical miles/hour); At altitudes in excess of 18 km (60,000 feet). http://www.armscontrol.org/documents/mtcr Would the GPS still be usable above 18 km or while travelling more than 515 m/sec? I have a Droid Charge.
|
No it's not. Commercial GPS receivers (like the one in your phone) only work below 18 km and below 515 m/sec. The rationale behind this is that this way they can't be used in ballistic missiles (yes, I'm serious.) In order to circumvent this you'd need to flash a different firmware to your GPS chip, if you didn't do this you're safe. No current android device ships with munitions grade GPS receiver.

I used ClockworkMod to wipe my Samsung Galaxy SII and install Cyanogenmod 9.1 on it. However, when I mounted my phone on my computer, I see that lots of folders were left on its internal SD by apps from before I flashed my phone. I was tempted to just delete everything on the internal HD from my computer (running Mac OS X 10.6.8), but I noticed there seems to be critical directories on it like one for Clockwordmod. Here is a list of the directories on the internal SD via ls -a: Are there directories in here that are essential to the normal function of the phone? A related question is: When I flash my phone, how to I completely wipe it so that when Cyanogenmod is installed, there will be no traces of previous activity as shown in the screenshot above? Thank you!
|
When doing a complete wipe, you can safely delete all directories off the internal storage. Generally, Android OS will re-create any folders on user areas like internal/external storage if it doesn't find them. You may want to hold onto (or at least back up prior to deletion) media folders like <code> DCIM </code> and <code> Pictures </code> , for example. Keep in mind that on different devices Camera apps may store photos and videos in other, non-standard directories. And of course do not delete the <code> clockworkmod </code> folder if you wish to keep the NANDroid backups you've made previously. Under normal operation, <code> .android_secure </code> is the only directory on either internal or external storage that is absolutely necessary. It contains apps that were "moved to SD" via settings (if external SD card is not present, apps get moved to internal storage instead.) If this folder is deleted, it will cause instabilities where these apps would not start (obviously), but you may also have trouble uninstalling them from Android, and would need to manually remove their left-overs (the caches, for example.) Another notable directory is <code> Android </code> - it contains data for installed apps.

Which directories can I remove in internal SD in Galaxy SII w/ Cyanogenmod?

android

I currently use the run-as command through adb to be able to access the data folder of an app that I am developing directly on my phone using AIDE. When connecting to the phone locally, using connectbot, I can find the run-as command in <code> /system/bin/ </code> but it has no executable permission. There are other programs/scripts in that folder that do have executable permissions and I can run them. My question is this. If I root my phone, I can change the executable permissions of run-as. If I then remove the root, will these permissions remain? I'm not totally averse to rooting my phone permanently but if I don't need to, I'd rather not. This is on a Galaxy Nexus. I'm aware if I leave run-as executable then I'm possibly allowing myself wide open for security risks. But I am willing to risk it, even just to see if its possible.
|
Yes. There's nothing magical to restore <code> /system </code> partition to original state. Many users gain root access temporarily to remove bloatwares from <code> /system/apps </code> & then unroot. But, remember, if un-rooting method involves flashing <code> /system </code> image, you'll lose your changes. So, use proper un-rooting method.

My phones screen will remain backlit and on while plugged in after getting a text or something that would pop up. Even if nothing popped up, if I just unlock it while plugged in, it will never re-lock on its own. This wasn't always the case but I didn't notice it for a while and am not sure what might be causing it. Maybe a background app? Works normally when not plugged in.

Check to see if "System Settings / Developer options / Stay awake" is checked. It's intended to give exactly that behavior ("Screen will never sleep while charging").

Is there any way to avoid pressing ok on the stock Android pin screen? There was an option to do this in cyanogenmod (9?) for my Nexus S 4G but it's not in stock (which I'm using now, unrooted). Is there any way to make it so that pressing the correct code automatically unlocks it, without having to press ok?
|
There's a reason why pressing OK has to be done and cannot be avoided is this - the PIN number can be of any length of your preference, and by pressing OK that is signalling the intention that There I have all the PIN digits entered, now Android, please verify! If there was a way to avoid pressing OK, that would impose the restriction on the length of the PIN digits used, once the length of digits is reached (for example the PIN can be four digits long ), then it would be automatic, but unfortunately in this case, no, you do have to press OK.

I am using LG P500 phone, running Android 2.3 (Gingerbread). I am installing SPB Shell 3D APK file which I got from internet. After some time it shows error that Memory Full, Please Uninstall Some Apps to Free Memory Though I have 50 MB Free memory.
|
50 MB is not much. Consider that for installation, the <code> apk </code> gets probably temporarily stored there (in <code> /data/local </code> (not always sometimes it's in the <code> /cache/download/ </code> folder) -- at least that's what the playstore app does, I'm not sure about a "local install" where the <code> .apk </code> probably is available from your sdcard) for processing, then gets installed (below <code> /data/app </code> ) and initializes its data (below <code> /data/data </code> ). And during all that, it should leave enough free space to allow all other apps to work normally: Creating temporary files, log files (at least the latter again being stored below <code> /data </code> in many cases, e.g those you can access via <code> logcat </code> ), and manipulate their data (guess where -- yes, again below <code> /data/data </code> ). So you see: Most of these actions take place on the <code> /data </code> partition. Now look what size the <code> .apk </code> of SBP Shell 3D has. Something about 10..15 MB? So when installed, it creates its data structure below <code> /data/data </code> as well, which adds to this. And during all that installation process, free space probably falls below 30 MB (if it really requires a copy in <code> /data/local </code> for the install, even below 20 MB) -- which is why the system alerts about "free space getting low". The solution already came with the warning: Uninstall some apps. Or move some bigger ones / rarely used apps to SD, if possible. Or clean up some cache -- but that will only help temporarily. You might also want to check some other space/installation related questions here: stackexchange-url ("Why is “insufficient storage” wrongly reported when installing an .apk via adb?") stackexchange-url ("Is there a way to workaround the phone memory limit for installed apps?") stackexchange-url ("Why can't I install apps when I have enough storage?") stackexchange-url ("Application doesn't get installed : insufficient storage available") could be good starting points.

I have a Huawei u8160 running Cyanogenmod 7.2 . I have a 500GB portable hard drive which is file system is NTFS , I connected the hard drive using OTG the phone didn't recognize it at all. So I was wondering if my Android system supports NTFS? and if it doesn't how can I make it supported? EDIT: I've formatted a flash drive to NTFS ,the phone detected it but it couldn't mount it,how can I mount NTFS file system on my phone?
|
I haven't seen any Android system supporting NTFS out-of-the-box. Could be some CustomROMs do, or there are some "root mods". So without root, it might get hard (though there might be some UserSpace mods as well, technically spoken). If your device is rooted, you could take a look at NTFS Mounter , which might or might not support your Huawai (take care to have a backup at hand anyway until you can be sure everything works as expected). Moreover, there was an article at XDA-Developers in June on Full NTFS Read/Write Support for Android you might want to read: According to the OP, he compiled a generic NTFS-3G driver for Android that should work on all ARM devices with a <code> fuse.ko </code> module. As it involves a kernel module to be loaded, it again requires root. And also again: It might or might not work on your device, take care for backups. A third source is Paragon's NTFS & HFS+ for Android (also available at Google Play ). Paragon is quite well-known with disk utilities on Windows, so I'd trust them to get the NTFS part right. But as you might have guessed: This tool requires root as well, plus the above mentioned fuse module. If you need more details, try the Google Search for "android ntfs" where I got above results from, all on page 1 ;)

I want to have both english and german prediction and auto correction at the same time for the stock keyboard (Jelly Bean here). My use case: Multi-tasking between english and german domains on my tablet where I both need the keyboard (e.g. Google Talk with my german friends and editing/answering questions on Android Enthusiasts in english). Problem: I don't want to switch off prediction/auto-correction nor do I want to switch to an alternative keyboard. At the moment I have to manually switch between en/de keyboards when I switch tasks (from Google Talk to the browser and back). This is annoying. I don't mind the keyboard layout (QUERTZ or QUERTY) but would prefer the english one. How can I have simultaneous multi language prediction/auto-correction in the stock keyboard?
|
The stock keyboard in Jelly Bean (4.1 or 4.2) does not support multiple languages simultaneously. However, SwiftKey, a third party keyboard, supports advanced predictions with up to three languages simultaneously. SwiftKey Official Website SwiftKey on Google Play Note that SwiftKey is a paid app. You can find the non-trial versions of the application in the Play Store. If you are looking for Swype-like functionality, note that an upcoming version of SwiftKey also includes it.

I have an Asus Transformer Pad tablet (TF300T). As with any other Android device I've owned, when I go to the settings menu and tap "battery", it gives me a detailed break down of which apps and processes are eating my battery power. Well, at least it used to do that. Nowadays, when I visit the battery settings, only 3 power consumers are listed: Screen Wi-fi Tablet Idle Here's a screenshot: Why aren't any of the apps I've been using listed? And what about system processes? One possibility that occurred to me is that nothing that is using less than 1-2% of the power is being listed, and all my apps are below the threshold. However, that seems unlikely to me as I've played dynamic 3D games and used other CPU-intensive apps at times, and after doing so I've checked the battery activity and they still don't show up. Before taking this screenshot I was using Pocket, Feedly, Mantano Reader Premium, Chrome, and Words with Friends for hours, alternating between them. Surely some of that should be shown here, right? When I check the battery activity on my cell phone (A Galaxy Nexus), I see Pocket has used 6% of my battery, and maps has used 3%. And I don't even use those apps on my cell phone nearly as much as I do on my tablet. Yet my tablet is completely silent about them. It also occurred to me that this problem may have started when I upgraded my tablet to Android 4.1 Jelly Bean about 3 weeks ago. But I can't be sure, and I don't know what to do about it if that turns out to be true. Can anyone tell me what happened to my battery usage data, and if there's any way to fix this going forward?
|
From what I recall, that report doesn't show anything that has used less than 1%. Considering how much of it is screen usage, I'll bet that that's the issue.

I have looked around and found no information on how Android manages to store passwords on the device. Especially Gmail passwords. I'm looking to learn how Android encrypts and stores passwords ? What key does it use and where is this key stored, and what encryption algorithm it uses.
|
Gmail's official app doesn't store password in your device. Your password is 100% safe if you use this app. This is how it works: The password is used by Google's authentication servers for the first time ONLY. After first successful authentication, an <code> Auth Token </code> is downloaded to device which is stored in <code> accounts.db </code> file as plain text. For all subsequent logins, this <code> Auth Token </code> is used, NOT your original password. So, if your device is stolen, all anyone can get is <code> Auth Token </code> which becomes invalid once you change your password. So, you'll be in ultimate command. For ultimate security, I'd recommend you to enable <code> 2-Factor Authentication </code> & create <code> Device Specific Password </code> for your device. After losing device, all you need is to disable that device. You don't even need to change main password. Note: These all aren't true if you use third-party email apps for Gmail viz. Stock Email app, K-9 Mail etc. IMAP or POP protocol needs original password to authenticate users everytime. So, plain password needs to be available to email app before sending it to server. So, most of email apps store passwords in plain text (hashing/encryption is useless because hashing/encryption key needs to be stored locally). In this case, I'd recommend you to enable <code> 2-Factor Authentication </code> & create <code> Device Specific Password </code> for your device. After losing device, all you need is to disable that device. Update: Technically, its possible to store passwords locally in encrypted/hashed form without keeping encryption key/ hashing key in plain text locally. Thanks to @J.F.Sebastian for pointing it out. Unfortunately, such implementation for Android isn't available yet. Starting ICS, Android provides KeyChain API using which an app can store a password locally in secure form. Apps using KeyChain API are rare, but stock email app uses it (Thanks to @wawa for this info). So, your password will be safe with stock email app as long as your screen is locked. Remember, KeyChain isn't safe if device is rooted and its not available on pre-ICS devices.

I am struggling with this kind of Google Apps -site, example from Google.com -site here . I use two email-clients in Android: default Gmail -client (because it is tied to my Gmail) and K9. I am able to set up all Gmails to K9 but one email i.e. the firm email from the site <code> https://www.google.com/a/firm.com </code> (excluding ofc the Android-tied-gmail -account, more stackexchange-url ("here")). It means that I am using K9 and default Gmail-Android -program but I would like to have all emails under K9. Is it possible and how can do it here in the case of the Gmails targeted to firms? I think such gmails are called something like Google App or something like that, not sure. The firm Gmail is not accepted like this in K9: Username: forname.surname Password: correct IMAP server: mail.myFirm.com Security type: SSL (always) Port: 993 Use compression on network: Mobile Wi-Fi Other If I change the IMAP -server to <code> mail.gmail.com </code> , it gets accepted but it won't work correctly -- redirection problem. But now I am stucked why it does not accept the above settings?! Perhaps useful to other like-minded stackexchange-url ("All emails under K9 -app?") stackexchange-url ("Email-client with Sent emails from many emails under IMAP?") Setting up IMAP over device-swarm that has a Debian Desktop -client, more here.
|
The default settings by K9 have at least two mistakes: use <code> imap.gmail.com </code> instead of <code> mail.gmail.com </code> . use full emails for usernames such as <code> [email protected] </code> , not just <code> forname.surname </code> . Example settings Incoming Email settings Username: [email protected] Password: correct IMAP server: imap.gmail.com Security type: SSL (always) Port: 993 Use compression on network: Mobile Wi-Fi Other Outgoing Email settings Outgoing Server Name: smtp.gmail.com Use Authentication: Yes Use STARTTLS: Yes (some clients call this SSL) Outgoing Server Port: 465 or 587 Username: [email protected] Some useful information extracted from this blog here .

Android requires at least one-working Gmail that is apparently tied to the default email. Now I would like to have that email under K9 but I cannot because Android instructs me to hard-reset my device if I remove the Gmail from the default Gmail. Now the problem is that I get two notification from Default client and from K9. So how can I have all emails under K9?
|
You don't need to remove default Google Account or factory reset to ditch double notifications. Use any one of following methods which suits you best: From <code> Settings </code> ~> <code> Accounts & Sync </code> , choose the default Google Account & turn off Gmail Sync . After that, you'll receive notifications from K-9 Mail, ONLY. In some Android versions, if you turn off all sync options listed under a Google Account, a Sign Out button is appeared. All you need is to tap it. Go ahead to try it. If you are rooted, delete <code> /data/system/accounts.db </code> file & restart the system (On Jelly Bean, its <code> /data/system/users/0/accounts.db </code> and the location can vary with Android versions). Next time, you'll be asked to add Google Account again.

You can, but a kernel mod may be required to also keep the host device charging. However, many devices are already prepared for this, and cables are being manufactured and sold to this specific end, as one can see from this Ebay search , there's already several cables in the market.

"Ok you bought a brand new mobile phone with brand new battery, after checking its working ok kindly switch it off and charge it fully (100%) then start using it. IT WILL INCREASE YOUR BATTERY LIFE.", said by the Seller. Is this a myth or absolutely true when talking about Li-ion batteries?
|
That recommendation from the seller was true for old batteries , and it seems they still keep saying that to customers! Nowadays, batteries are often <code> Lithium-Ion </code> or <code> Lithium-Polymer </code> and such batteries (as I have read many times and based on my own experience) would be stronger if you charge them often. The first time charging and " wait-until-full-discharge-before-recharge " and " don't-use-when-charging " are not applicable to these modern batteries. Li-Ion and Li-Polymer batteries, if charged often, after about 1 month, would reach to their maximum performance, and you are recommended to charge them every time you find an outlet! In stock Help application of my Sony Android device, In a section about Battery Life, it reads: Charge your phone often , This will not affect the lifespan of the battery.

There are native programs available on Android for creating file systems, and in most cases they reside in a directory below <code> /system </code> (my Motorola Droid 2 e.g. has them in <code> /system/xbin </code> . Depending on the file system you want to create, you can chose between: <code> mkfs.ext2 </code> <code> mkfs.minix </code> (unlikely you want that -- and it might even be not available with your ROM) <code> mkfs.vfat </code> As the latter is probably what you want, some closer explanation on its options here: <code> mkfs.vfat [-v] [-n LABEL] BLOCKDEV [KBYTES] </code> What do those options stand for? <code> -v </code> : Generate verbose output (reporting) <code> -n Label </code> : Give the file system a name <code> BLOCKDEV </code> : the file system you want to format <code> KBYTES </code> : probably the block size (I'm not 100% sure with this) So the minimal thing to do would be: <code> mkfs.vfat -v /dev/block/uba1 </code> (provided your drive to format is available as <code> /dev/block/uba1 </code> on your system). One more example, giving the file system a name: <code> mkfs.vfat -v -n MyNewDisk /dev/block/uba1 </code> It should report success then -- or an error if it failed. EDIT: On some systems, the <code> mkfs </code> commands seem to be part of the <code> busybox </code> binaries -- which you can recognize with a full directory listing, e.g. <code> ls -l /system/xbin | grep mkfs </code> It should show them as "symbolic links" pointing to busybox then. In this case, you can optionally run them via busybox: <code> busybox mkfs.vfat </code> should show you the syntax then (thanks to ce4 for pointing this out -- credits to him ;) ).

I fear that if I reset my phone to factory defaults I'll never be able to access my Google Account again, since I use the Google Authentication app on it to provide the 2nd step of the verification. Am I right? Should I remain worried?
|
There are several ways to address your concerns. First - you should print the emergency codes. Google has good directions on how to do so here. (reproduced here) Sign in to your accounts at https://www.google.com/accounts/SmsAuthConfig. Look for the “Printable backup codes” area. Click Show/Generate codes. If you are fine using the current set of backup codes, you can print or download them. If you believe this set of codes might have been stolen or you’ve used many of the backup codes, you can generate a new set by clicking Generate new codes. Second - Even without backup codes, you should have supplied your phone number to Google at some point; this allows for you to have a temporary code sent to you in a text message. As shown in the following image: Thirdly - You can disable 2-step verification while Wiping your phone, and re-enable it again after completion. (This requires you to set everything back up). Google Instruction Page to Disable 2-Step Verification (steps reproduced here) Visit the Using 2-step verification page under your Google Account settings. Sign in with your username, password, and verification code if prompted. Click Turn off 2-step verification. A pop-up window will appear to confirm that you want to turn off 2-step verification. Click OK.

I have a Huawei u8160 running Cyanogenmod 7.2 . my phone is giving inaccurate readings of the battery charge level (e.g one day morning it was 33 that day evening it became 34 without touching the phone) is that an indicator of malfunctioning battery,or the sensor is reporting false readings?
|
It is not very uncommon for Cyanogen to have some problem with battery status reading. Things you can try: Turn off the phone and take off the battery for a while; Let the battery fully drain and then reset the battery calibration on clockwork recovery; Try an app like this . I'm not sure why, but when I changed my battery visualization to a percentage view instead of the default (in the Cyanogen configuratons), the battery lectures of my smartphone started to give me wrong readings. When I switched back, it got back to normal after a fully recharging.

I'm searching a way to maintain RTF files for open/editing but at least for reading, because I have no support for it on my device. I tried mobile docs view and yozo office but they didn't support RTF.

To read RTF files you basically just need and app that supports that file format. Here's a good one that additionally supports many other document types: Cool Reader by Vadim Lopatin available from Google Play Store. Reading books in epub, fb2, txt, doc, rtf, html, chm, tcr, pdb, pml formats. eBook reader. Supports epub (non-DRM), fb2, doc, txt, rtf, html, chm, tcr, pdb, prc, mobi (non-DRM), pml formats.

I have the Samsung Galaxy S2 T989d and my phone is stuck in a bootloop with CyanogenMod. I want to get some pictures off of the internal SD before I wipe it and install the stock rom. I tried getting them off of CWM by mounting my phone but it doesnt work for some reason. I can mount my micro SD from my phone but I can't mount my internal memory. Help would be deeply appreciated!
|
Wiping or performing a factory reset via CWM shouldn't touch any of the data on the internal sd card. However, performing a factory reset from within the ANdroid settings will wipe all personal data on the SD card. Use ODIN to flash a stable version of either the Stock ROM or one designed especially for your device. That should at least allow you to boot the phone normally.

I am struggling to set up graphical email-client program in Debian, more here and here. I have a similar problem with Android. I would like to see Sent -emails in my android phone. How can I see my sent -emails in my Android -phone from many email -addresses? Profile I use IMAP. I have currently many devices such as laptop, Android and iPad -- to manage the same emails (some odd lag every-now-and-then). I have many email -addresses connected with apps such as Gmail -app by Google and K-9 Mail where I use IMAP.
|
As with IMAP mails are stored centrally on the server, you can see all mails from all IMAP clients. You can automatically store sent mails to a "Sent" folder (instead of only send them and not storing them), which is configured on a per-client basis. I cannot tell for your desktop clients how to do this, but with K9 you can select the folder in Menu → More → Settings → Account settings → Folders → Folder for Sent objects Just in the Folders menu, you will find some more special folders you can define (e.g. for drafts). Having your "Sent" folder defined on all your clients (and always having defined the same ), you should be able to easily view your sent mails from all clients, regardless of the fact from which client a mail was sent.

There's two ways of doing this: The intents used can be searched throughout the entire source of CM available on github , notably <code> frameworks/base/core/res/AndroidManifest.xml </code> and general <code> grep </code> ping of the source. <code> adb shell dumpsys | grep "Action: \"android.intent.action" </code> The second option is the easiest - from AOSP here's a list of the intents...

Whenever I install a new widget, I don't know if it supports ICS or not immediately because it won't show up on the Widgets tab until I restart the phone. It is highly inconvenient. Is there a way to force Trebuchet (my home app) to reload the widget list everytime I install a new app?
|
In my experience, Trebuchet does always reload the list. I just have to wait a couple of seconds. If it really doesn't, you can go to the Applications section in the settings menu, select Trebuchet and Force Stop it. That should force it to drop any state, including the widget list.

When I move my applications to the the sd card using the "Move To SD Card" feature in ICS the widgets for particular application stop working it says "Problem loading widget".Does anyone know a solution to this? or do I just have to keep the application in the internal memory for the widgets to work?,
|
There are some technical reasons explained on the Android developers website that justify why the widget may have stopped working: Any of this ones aren't recommended to move to an External Storage due to possible failure: Services Your running Service will be killed and will not be restarted when external storage is remounted. You can, however, register for the ACTION_EXTERNAL_APPLICATIONS_AVAILABLE broadcast Intent, which will notify your application when applications installed on external storage have become available to the system again. At which time, you can restart your Service. Alarm Services Your alarms registered with AlarmManager will be cancelled. You must manually re-register any alarms when external storage is remounted. Input Method Engines Your IME will be replaced by the default IME. When external storage is remounted, the user can open system settings to enable your IME again. Live Wallpapers Your running Live Wallpaper will be replaced by the default Live Wallpaper. When external storage is remounted, the user can select your Live Wallpaper again. App Widgets Your App Widget will be removed from the home screen. When external storage is remounted, your App Widget will not be available for the user to select until the system resets the home application (usually not until a system reboot). Account Managers Your accounts created with AccountManager will disappear until external storage is remounted. Sync Adapters Your AbstractThreadedSyncAdapter and all its sync functionality will not work until external storage is remounted. Device Administrators Your DeviceAdminReceiver and all its admin capabilities will be disabled, which can have unforeseeable consequences for the device functionality, which may persist after external storage is remounted. Broadcast Receivers listening for "boot completed" The system delivers the ACTION_BOOT_COMPLETED broadcast before the external storage is mounted to the device. If your application is installed on the external storage, it can never receive this broadcast. Copy Protection Your application cannot be installed to a device's SD card if it uses Google Play's Copy Protection feature. However, if you use Google Play's Application Licensing instead, your application can be installed to internal or external storage, including SD cards.

I want to disable the sound/vibrate effect when typing a message in Ice Cream Sandwich. I have disabled it in <code> Settings > Sound </code> Now there is no touch sound when I am typing a phone number or selecting an application to run, but there is still sound/vibrate when I type messages. How can I disable that too?
|
On vanilla Android you do this by going into <code> Settings -> Language & Input </code> and then pressing the settings button to the right side of "Android Keyboard" (or, generically, whatever keyboard you're using). There are two checkboxes on the keyboard settings page, one for "Vibrate on keypress" and one for "Sound on keypress". Uncheck both of these to disable the keyboard sounds/vibration.

It allows you to "mark" a card. It is a kind of bookmark that allows you to find this card easily later. The most common case is when a card needs editing, but you do not have time/tools to edit it right now, so you mark it, and you will fix the card when you are back home. Why not edit the card right away, instead of just marking it? Examples: You are reviewing in the bus, and you notice a kanji that you probably entered wrongly, so you need to check. But you need the library's huge kanji dictionary, which is too heavy to carry in the bus. You realize you made a typo when entering a LaTeX formula. You will only be able to fix it next time you are at your desktop computer. You have a doubt about a card, and must ask a native speaker, but there is none around.

The progress bar being stuck for a while is not unusual as progress bars are fairly difficult to get right. An update taking more than half an hour, on the other hand, doesn't sound right to me. Of course your phone could simply be slower at this task than mine.

I have the SyncMe app, and I would like to have a widget activating a fuction in the app. Now I have to open the app -> Click on a button -> Click on another button. Can I have a widget doing this by just clicking it?
|
In short , you can't. Only the application can interact with itself internally, unless an API was created for that end. External applications aren't able to know what to do in order to follow your desired "path". The best you could achieve is opening the application, but you still needed to manually tap the buttons. My recommendation: I believe you are trying to have some sort of "Sync Now" functionality without having to open the application and clicking some buttons to achieve that. Either case, Email the developer and request such widget, I'm sure it's useful enough and interest will arise.

I'm getting the alert "Phone storage space is getting low".

In fact, after installing cyanogen it only had 1mb free. I actually deleted some system apps (wallpaper crap mostly) to free up a little more. I am not asking how to get rid of the alert. I want to know which specific storage space does the alert refer to?
|
It is usually <code> /datadata </code> that gets full on the Galaxy S. Interestingly this partition is not displayed in the <code> Storage </code> Setting Menu. The quirk is that /datadata is mounted on a special very fast flash chip that only provides 170MiB of storage space. While this was enough in the "early days" of Android when the Galaxy S was released, it can easly become tight with modern Apps. <code> /datadata </code> is used to store application user data, and while many apps only place a few KiB there, some apps require to store more. Typical candidates that store around 20MiB in <code> /datadata </code> are Google Chrome and Google Currents. ATM the best practice is a fix that lets you control which apps can store data on the fast chip and which are outsourced to the slower RAM. This script can also be installed with an app called datafix. To find the apps that consume the most space use <code> su && du -s /datadata/* |sort -gr |head </code> . For example on my device: <code> shell@android:/datadata # su && du -s /datadata/* |sort -gr |head 39180 /datadata/com.android.chrome 20809 /datadata/com.google.android.apps.currents 16763 /datadata/com.google.earth 9431 /datadata/com.google.android.apps.plus 8938 /datadata/com.inisoft.mediaplayer.a 8270 /datadata/com.google.android.apps.maps 3015 /datadata/com.google.android.apps.docs 2160 /datadata/udk.android.reader 2096 /datadata/com.android.providers.contacts 1597 /datadata/com.fsck.k9 </code>

I have a Samsung Galaxy Ace GTS 5830i. I somehow messed up the power button of my phone and now after the battery drained completely, It will not start. I tried looking up online for going into recovery mode (without using the power button) i.e keeping home key pressed while inserting the charging but nothing works. Finally, I thought I must have an option to boot up my phone through Eclipse DDMS but I cant find any option there either ( See screenshot ) Please help. EDIT : Thanks to the answer by Sparx, I have solved this problem. Connect the phone via USB to your computer. If you have installed the Android SDK, go in the android-tools folder and execute adb devices (if on a mac, run ./adb devices) If your devices shows up in the list run ./adb reboot
|
Have you tried plugging in the charger? or else plugging in the charger and while plugged in, remove and then re-insert battery. Some phones tend to start up in that manner. Also if you can connect via adb (even if your phone is powered down), the <code> adb devices </code> followed by <code> adb reboot </code> ought to start your phone. If you're rooted, there are apps like Quick Reboot that allow you to reboot to Recovery or Download mode with a tap, provided you have CWM.

I installed CyanogenMod 10 Nightlies on my Galaxy S1, coming from CyanogenMod 9. On every reboot I get the message: Warning! A problem was detected with your device. Your device IMEI number is invalid. And invalid IMEI number could cause network issues including the inability to call emergency numbers. Sometimes I have network issues and my handy just won't connect to the Internet(even though it shows E/H Connection) I once made a backup of my <code> /efs/ </code> partition, I already restored it but the message still appears.
|
FYI The CyanogenMod 10 is the first update with the code to detect an invalid IMEI. You could already have an invalid IMEI and don't know about it. The issue with an invalid IMEI is that you may have emergency calling problems (inability to do emergency calls). Confirm IMEI Does the IMEI reported match the number under your battery? Dial <code> *#06# </code> and the IMEI will be presented on your screen. Possible Solution From this code.google.com thread, the user at comment 5 managed to solve the issue: Steps I took to solve the problem: Flash my phone by Odin to version 2.2.1 Update to CM9 using Recovery with stabile version od CM9 http://download.cyanogenmod.com/get/jenkins/5805/cm-9.0.0-galaxysmtd.zip Update to CM10 using last version of kernel. I used cm-10-20120822-NIGHTLY-galaxysmtd. Between steps I did wipe data/factory reset and wipe cache partition. Now my IMEI is correct. After cleaning the phone and updates do CM10 I recommend installing gapps-jb-20120726-signed, because your phone will be clean as a baby after birth.

I got my Galaxy Nexus and now I'm stumped how to get my contacts right? There's no phone book anymore here. These are just my Google contacts of which I have just a handful with phone numbers. What's the best way to get my phone numbers into those contacts without editing every and single one? So merging phone numbers on my SIM with google contacts. Add new that are missing in my google contacts but are present on my SIM? Why can't I have separate phone contacts from Google contacts? And what's the rationale behind the decition they've made with this? Is it also possible that phone-only contacts (with name of course) woudl not show on my gmail afterwards? I mean on the web. On my computer...
|
Rationale The traditional concept of mapping names to numbers which many people know from cell phones doesn't really apply to smartphones. Here the idea is that there is one central instance, the contacts app, that holds information about your contacts and how you can reach them, which could include a phone number but not mandatorily. Often there is also e-mail, third party messaging (whats app), third party VOIP (skype) social (micro) blogs (Twitter, Google+) or various social networks. (Facebook, LastFM, ...). Use stackexchange-url ("www.google.com/contacts") stackexchange-url ("I recommend to move all information about contacts that is stored on your SIM card to the Google contacts.") Furthermore Gmail will only show contacts that have a e-mail address. So there is no need to have something like phone-only contacts. The cloud idea is to have every piece of data (or information if you want) everywhere available. Why do you want to have some contacts just on one device? I know it's hard for some people that their contact app suddenly shows hundreds of contacts from different sources, but Google/Android provides techniques to deal with that too: Use contacts groups. Most Google software is able to show only certain contact groups (but will run contact searches for the whole contact set).

I want to be able to switch from CM7 to CM9 and vice versa without losing my apps and data everytime. Is it possible to make a dualboot?
|
Making a dual boot is possible, there's a nice app for that end available from Google Play Store. Boot Manager Pro (2,17€) and the Boot Manager Lite (free) , both from Init 2 Winit Apps . Boot Manager is Android's first multi-boot application. It allows you to install boot ROMs from your sdcard and boot between then with just a reboot. The application acts as your recovery for your sdcard slots. Install your kernels, themes, and ROMs all through the app and use your normal recovery for your phone ROM only. Unfortunately, I haven't found any supporting information if this will or will not share apps between ROMs, but at the very least it solves the dual boot problem. Ps: Since apps when installed on the SDcard still leave a portion of their code on the main installation directory of the current ROM, it doesn't seen possible to have apps shared across different ROMs.

Chrome is the default on Jelly Bean OS. When I bought Nexus 7 tablet it came preinstalled with JB, but when my Galaxy Nexus got upped the old stock browser is still present. How can I get rid of the stock browser on Galaxy Nexus in JB? Is it at all possible?
|
This does not really remove the app from your device, but "freezes" it (i.e. makes it "hidden", so it no longer shows up in your App Drawer etc.): From your Homescreen, open the menu and go to Settings → Apps → Browser , and there hit Disable . If you later decide you want it back: Same path, and Enable it again.

My HTC Incredible (Verizon) has tried to update to either Ice Cream Sandwich (android 4.0.x) or just build # 4.x (I'm not sure which) for the past two weeks or so. Either way, it has not been succesful. Sometimes I'll get a notification telling me that the update has been downloaded, and asks me whether I wan't to reboot to install. I tried that a bunch of times, but neither time did it even shut down after the ten second delay/grace period. Once I tried going to Settings > About Phone > System updates, and downloaded the update and tried to install, but the same thing happened: ten second countdown, then nothing. Now, the notification never pops up, and Settings > About Phone > System updates indicates that no new updates are out. What's happening? Thanks!
|
I have had this problem with previous OTA updates on my HTC. The problem I ran into is that my phone didn't have enough "space" for the update to actually install gracefully. The bigger problem is that there are many different places the phone can run out of "space". I ended up booting into the recovery to wipe the cache partition (for some details see stackexchange-url (""Low on space" warning with over 50% free")). I also ended up wiping the app cache and data on a number of apps (including the launcher -- lost all my icons, gmail, maps, etc) to reduce "space" used until the update installed. I don't recall what exactly pushed the install over the edge and made it go, but it was painful enough that I'm not bothering with the latest update (its just a point release, despite the version number they're showing you its not an ICS update).

I have Galaxy Nexus with JB. I got stock browser on it and Chrome and I also installed Firefox just to keep it there since I'm a developer and I can test stuff on all three. But the question I'm having is, what happens if I set a particular browser as "always" when it asks me which one I'd like to use? I keep pressing "just once" because I don't know hot would I change it later if I desire to do so? Is it possible to change/reset this later? How? Does "always" set it as default just for that particular app that's redirecting to browser or does it set OS-wide?
|
Disabling the default action for an intent is easy enough to do on ICS. From the launcher, press the menu button, and choose <code> Manage apps </code> . Select the app that you chose as the default for the action. Scroll down and touch <code> Clear defaults </code> .

System apps are stored in the /system/ partition. You can only uninstall them if your device is rooted (See: stackexchange-url ("How do I root my device?")).

I'm trying to access a web server running on the Android emulator from my machine. I know the reverse i.e., how to access the server running on my local machine from the Android emulator (using <code> 10.0.2.2 </code> ). I have searched a lot about this stuff but couldn't get any relevant information. When the server is up and running inside the emulator I can access it using <code> 10.0.2.15:portNumber </code> . I can do a telnet to the emulator, but I wonder how that will be helpful. Any suggestions on how to get connected to the web server running inside the emulator?
|
You need to create a port forwarding to your Android device. This can be done with ADB. <code> adb forward <local> <remote> - forward socket connections forward specs are one of: tcp:<port> localabstract:<unix domain socket name> localreserved:<unix domain socket name> localfilesystem:<unix domain socket name> dev:<character device name> jdwp:<process pid> (remote only) </code> For example: run <code> adb forward tcp:12345 tcp:23456 </code> and then use the URI <code> http://localhost:12345 </code> to access the server running on port 23456 in the emulator. Note that some ports are reserved for Android and some can only be used after rooting, so I'd suggest using high ports (> 20000) if you can.

My daughter loves to share videos on YouTube with her friends. As a result she's blown through her monthly 2GB data allotment on multiple occasions. While I've educated her on the difference between 3G and Wi-Fi, and she's a smart kid, it would simply be easier if I could limit her YouTube app to only allow streaming while on Wi-Fi. I looked in the app settings but unless it's in some weird location there is no such setting. How can I prevent YouTube streaming to be only allowed on Wi-Fi? (If it matters: Droid Incredible 2, Gingerbread)

Don't know of any YouTube option for that end, but if you are open to use an app to limit other apps, you can give a go to Onavo Count | Monitor Data that has an option to limit the app to Wi-Fi only: Save money on your mobile bill - avoid costly overage fees!

I'd like to remap the physical menu key of my Xperia Neo V running Cyanogenmod 9 to multi-tasking, the way it is on phones that were launched with ICS or Jelly Bean to begin with. Apps built for ICS would then display the action overflow. With older apps, I guess an on-screen menu key would appear -- I think there is in fact an ICS phone that does this as it has only two keys, but I don't remember the name. Alternatively, the menu key would stay a menu key in these apps but this might be more difficult to achieve. Is there any way to configure or modify Android to behave this way?
|
As I have just discovered, the latest Cyanogenmod 10 nightlies have this feature. Unfortunately it doesn't ever display an on-screen menu key. As a workaround, I mapped long-press of the menu key to its old function.

Just grabbed a phone with 4.1. Most questions talk about the Google Listen app, but I can't find it. Did google remove the "podcasting" feature from their Play suite?

Yes, on August 3rd 2012 Google Listen was discontinued and is no longer available on Google Play. If you already have it, it will continue to work, but on November 1st 2012, the Podcast Search will cease to work. This project was very limited in functionality anyway. There are other apps out there that are updated and actively worked on. I think the last time Google Listen was updated was a couple months after it came out in 2009. A lot of the podcast apps out there now can make use of the "Listen Subscriptions" folder that is in Google Reader. This is where Google Listen stored your subscribed podcasts. I continue to use Reader to store my podcasts in this location, then I import it to the player on my phone.

Do any good file servers exist for Android that do not require root? Ideally, it'd be nice to just be able to have an SMB share, but the only app I was able to find for this ( Samba Filesharing ) requires root. I'm currently using FTPDroid, but it's pretty slow (I'm getting about 200 KB/s downloads on my n600 wifi). Are there any better options? I'm using a Verizon Galaxy S3.

There are tons of alternatives. Find a list of FTPServers in this German thread ( Google Translate version ), others like WebDAV and Samba can be found here (again: Google Translate version ). I'd say you could give FTPServer a try, sounds promising. No root mentiones, highly rated. Alternatively, you might want to try DoMobile FTP share (very small: less than 30 kB!) or their new app eShare . Meanwhile I even managed to locate SwiFTP again (somebody continues the project, finally!), which should be fast and lightweight.

There are apps that can backup your bookmarks, e.g. GMarks or TitaniumBackup (needs root). You could also sync the P500 bookmarks with Google (by default on) and also set up sync for a regular desktop chrome browser (very prominently accessible in the settings). You should be able to export your bookmarks then.

I was playing around on my Nexus 7 today and somehow ended up in a landscape version of the homescreen. I haven't downloaded any apps that mess with it like Ultimate Rotation Control, or rooted it or anything. Somehow though, it was in landscape and I thought it looked pretty cool. As soon as I switched into a different app and came back it was stuck in portrait again though. Does anybody know how that would have happened? I'd like to at least mess around with it in landscape, especially since it seems to be built in. EDIT: It looks like if you open mVideoPlayer and lock the screen, then it will open up to the landscaped homescreen when you unlock. However it rotates back. It doesn't look like the orientation being in landscape messes up anything, so why would it be locked in portrait? EDIT: The above method worked the first three times but doesn't seem to do it at all anymore.

More of a status update than an answer: Jelly Bean 4.1.2 allows a landscape rotation on small screens. I previously had the same experience (accidentally changed the rotation but could not reproduce it) -- I received the system update yesterday and was pleasantly surprised after the reboot :-)

When using aLogcat to view my Android log files, I find very few messages showing up in any of the views. Selecting Verbose level and no filter, I see that Main contains mostly garbage collection debug and info messages, but I rarely more than about 20 messages every minute. Events mostly contains info log messages from alogcat itself, at about the same rate, while Radio remains steadfastly empty. Being relatively new to Android, I wonder whether this is normal. Is this rate typical of the main system log file on Jelly Bean?
|
Not very active if you use apps like aLogcat. The permissions system regarding to logs was changed with Jelly Bean: The permission to read logs "READ_LOGS" is now systemOrSignature, which means that an app that is not signed with the ROM/system key can only view its own log. You can still view the full android log with <code> adb logcat </code> from the SDK. I think that this was a long overdue change in the log system.

I know it's been asked here how to prevent applications from using data connections. But that is not my intent. I have a Galaxy Nexus running Jelly Bean 4.1.1 and I would like to restrict most of applications to use my data connection. But would allow some to use it. For instance I would like to restrict Currents, Google+, Facebook, Maps and Google Now from using my data connection. But I would like GMail and Talk to use it. How can I do this? And is it also possible to set sync frequency when wither on Wifi or Data connection?

Go into <code> Settings | Data usage </code> . Then in the <code> Mobile </code> tab, you'll find a list of the applications that have recently used data. Click on any of these applications and there will be a checkbox to restrict background data while the phone is using a mobile connection (as opposed to wifi). I'm not aware of a way to control the sync frequency.

I guess this has to do with our habit on desktop computers where we open an application use it close the application AFAIK there's no direct way from within the application to close it. And by pressing the Home button app just gets into the background. Still running. I got a habit of pressing Home, then Recent apps and flicking all open apps out. Is this a bad habit? Should I leave applications like GMail, FB, Currents, GNow, etc. running or is it better to close them and have as less apps as possible running?

From a developers point of view (my point of view): Application's on Android work a specific way, they all have their own life cycle, the main ones we are talking about here is when the application is paused, or stopped (onPause, onStop) and when the application is destroyed (onDestroy), these two states are brought to light in different ways, onPause is when the user can no longer see the application, or screen, this is when the user presses home or clicks something on the screen that takes them to another screen, like pressing a link for example, there is still a possibility of you needing this screen, for example when you press the back button to get back to the screen, you still want it in the same state, so the application is still open and waiting for you to return. The other state, when the application is destroyed, can happen three ways, firstly the developer might of added something in to close the application automatically, for example the Endomondo application you can press menu > exit, this will "close" the application and it will no longer be in memory. The next way is the user pressing back on it, as in there is no way to get back to the exact screen (for example you can't press forward to get to it) so the application is no longer needed so it is closed. The third way that an application is destroyed, or closed, is when Android needs more memory, when this happens it clears the applications that haven't had interaction the longest. Android does this itself, if it needs more memory it will get it. So in all leaving applications open isn't a bad happen, however some applications can still use a lot of CPU power and not memory when its in the background, if you think this is going to happen you should close it yourself, android should be able to pick up on this however Have a look here at the states of a activity, or a screen: EDIT: Pressing back on a screen: Activity destroyed ( <code> onPause > onStop > onDestroy </code> ) Swiping application away on recent apps: Activity destroyed ( <code> onPause > onStop > onDestroy </code> ) Pressing home: Application kept in memory, only if the developer hasn't added a self close feature ( <code> onPause > onStop </code> ) Navigating away from app, link etc: Application kept in memory, as above ( <code> onPause > onStop </code> )

In the area where I live I sometimes have trouble with reception. The Internet stops working for me or it takes time to load pages. The phone tries and tries to connect. It seems to me that when this is happening it depletes the battery much more quickly. Is my observation correct?
|
Cell signal To add to ce4's answer: You can check that for yourself. If you take a look at your battery stats (they are always at a little different place in the system menu: Sometimes in the main menu, other times under phone info ), it lists the apps which used most of your battery. One of the highest consumers in there is most likely your display -- and close to it you'll find an item cell standby (sometimes called phone standby ). This describes how much battery was used to "keep the signal". Check that in times of good reception versus those of bad reception and see how much it differs. Network stuff This can even be "multiplied" if you have many apps running services to poll information from the net permanently -- like email apps using IMAP idle, or some social chat app keeping a push connection. It looks like the same is happening here: it tries hard to keep the connection, and thus pushes the cell radio further. Due to the bad reception, the connection gets slow, and those services keep longer "wake locks" (keeping the CPU alive to complete their task), which again eats battery. How to find out if your reception was good? The system does in fact provide this information (at least from Android 2.3/Gingerbread on), in the very same battery statistics mentioned before. On top of the first page you find a small graph 1 : tap on it, it brings up a bigger one 2 . The screenshots are in German, but you still can tell the details: In the first 1 , you see the cell standby titled "Mobilfunk-Standby" right next to the Display, as said before. On top of that is mentioned "mini-graph". That tapped brings you to the page where you find the second image 2 at the bottom. Here take a look at the first graph, titled Telefonsignal ( phone signal ). "The greener the cleaner": A bright green means "good reception" (the screenshot shows this at the begin and end, that is here: morning and evening -- so at home I have good reception). Getting yellowish: "Moderate reception". This uses more energy: compare it with the graph on top of it (not in the screenshot -- but the same as in the first screenshot), and you see the bar is almost flat where the cell signal is good -- but falls faster where it's not. See the little red spots: "no reception". And phone will power-up like crazy to find a new cell tower... How to find out where the dead spots are? Here we need to use 3rd party tools. I will mention two of them here: No Signal Alert 3 and OpenSignalMaps 4 . Both can alert you when entering a "dead zone": No Signal Alert lets you view a log of cell state changes, plus can show you a map of where the dead zones were 3 . OpenSignalMaps has the plus of showing you all cell towers in reach 4 , pointing out which you are connected to. It also offers you a "compass" giving the direction to the strongest signal. How to automatically deal with those dead zones ? There are some little helpers available which watch your signal. If it drops or gets lost, they simply switch the radio off (so it cannot further power up searching a non-existing signal) -- and periodically activate it again to check whether the situation has improved. One of them is Battery Saver 5 , which also lets you define profiles so you can easily switch other things like Wifi. Then there are more powerful "automaters" like e.g. GreenPower free battery saver 6 , which even manage a lot more. And these two are not the only ones...

Splitting this question from the comments to stackexchange-url ("my answer") to stackexchange-url ("How to install ClockworkMOD Recovery on Sony Xperia Neo V (MT11a)?") Erik, one last thing. I accidentally made an extra backup which didn't even complete because my SD is full, how do I delete that backup, or any other previously done backup using CWR?
|
Clockworkmod stores its backups in <code> /sdcard/clockworkmod/backup </code> (replace <code> /sdcard </code> with the path for your external card if you're looking for backups to external memory). With versions prior to 6.0, you can move off (or delete) the entire directory to clear space. The entire backup is self-contained. If you're using a 6.0 or greater version of Clockworkmod, this is no longer the case. The information about the backup is still in <code> /sdcard/clockworkmod/backup </code> , but the actual data is now stored in <code> /sdcard/clockworkmod/blobs </code> and is deduplicated between backups. The upside is that this should save some space between multiple backups. The downside is you can't just move off or delete a backup directory. With 6.0+, you now have to delete that folder, and then run the "free space" option. Initiating a new backup will automatically free space.

Since aLogcat now stackexchange-url ("no longer works with Jelly Bean"), how can I access the system log files on my device without either root access or attaching it to a computer? I stackexchange-url ("have tried") using <code> adb logcat </code> from my PC and that worked fine, so I know that plenty of messages are being logged. Using <code> logcat </code> from Android Terminal Emulator on my Nexus 7 shows almost no output though and <code> adb logcat </code> from Android Terminal Emulator , starts the daemon but then just says <code> - waiting for device - </code> and nothing more appears. So, is it possible to access android log files on my Nexus 7 without root access ?

No, for security reasons it is not possible to access android log files on the Nexus 7 (or any other device running Jelly Bean or higher) without root access. Google changed that with Jelly Bean. I'd suggest you wait until logcat readers like aLogCat and such get fixed (i.e. they will require root access to show all logs then). From AISEC-TR-2012-001-Android-OS-Security.pdf - 3.3 Android Permission Model : The READ_LOGS permission can substitute the following on many devices, depending on the Android version and thus the standard apps’ versions installed: READ_CONTACTS GET_TASKS – every started Activity is listed in the system’s logs READ_HISTORY_BOOKMARKS – opening new web pages is a browser Activity and thus logged READ_SMS All solutions below require root access : You need to either run logcat as root in a shell or manually grant it via the shell pm command (root required) works also (see XDA , exchange org.jtb.alogcat.donate with the app's pkg name): <code> pm grant org.jtb.alogcat.donate android.permission.READ_LOGS </code> This is for the lazy ones and not suggested: If you're desperate, careless and lazy, you can fix it by giving every app the READ_LOGS permission by applying this ugly and insecure hack ( Chainfire via twitter ): <code> chmod 04755 /system/bin/logcat </code> To quote CyanogenMod developer Koushik Dutta's G+ post : Did the Android Log permissions/behavior change in JellyBean? It seems that if an application runs "logcat" now, it can see only the log entries created by its UID. Log lines from other UIDs are not shown. Basically, it seems to be filtered now. I have the same permissions as usual. Also confirmed the same thing is happening in other log collector apps.

The vibrate strength of my Galaxy Nexus is incredibly weak. When I have the phone in my pocket I simply don’t feel the vibrate for incoming calls at all, which defeats its purpose. I’ve missed more than one important phone call due to that. Is there a way to increase the strength? I haven’t found anything relevant in the settings.
|
AFAIK, the vibrator motor that are used in the phones are called Q-Coin motor as they are in a shape of a coin. They are of permanent magnet type accepting two leads for positive and negative DC voltages. The circuitry that operate this motor just can switch on the motor for a specific period of time and can change its rotation direction. All other parameters of vibration are set by motor's design. Hence, for your need the amplitude of the vibrator motor has to be increased to make you aware. And unless the motor itself is replaced, this can't be done in my opinion. This is a specification of such a motor and you can see it's details. UPDATE: After searching Google, I stumbled on more info about these motors. With that information, it seems that there are two types of such motors. One being fitted with an eccentric rotating mass and another being a linear actuator (working more like a speaker). The article about linear actuator says that this is the present trend and beautifully explains how the motor works. If the Nexus device that is in question is vibrating at its maximum amplitude, then there is no way any software component to increase its amplitude. Other way, if device is NOT vibrating at its maximum, then by increasing the applied voltage there is a possibility to increase the amplitude. Thanks to @Konrad Rudolph who made me to know more about this motor.

There is AirDroid, but it is Focused on contacts/messages/files, not on settings Too Web 2.0-ish, not easy to script I want a simple tool to build my own solution with instead of mis-using some user-oriented application. It should listen some HTTP port and allow to turn on/off wifi, take photos, pause/resume music, adjust volume adjust brightness (and so on) without any bells and whistles, so I can control the device using simple requests like <code> curl http://localhost:8080/wifi/on </code> or <code> curl http://localhost:8080/music/pause </code> . /* Actually I want good and easy android control from Linux command line tools, but remote HTTP control tools seem more likely to exist, so asking about them */

The best solution if you're willing to write code is SL4A . This will give you the most flexibility. You could use the Python module with a lightweight web framework (like: bottle.py ) or your favorite scripting language. As a side note, get requests should not change state. Also make sure you implement some sort of security as this would make it possible for anyone to control your phone remotely.

I have a rooted HTC Hero, and what I want to do is to enable the adbd to listen to a port at boot time. I tried some code found here : <code> setprop service.adb.tcp.port 5555 stop adbd start adbd </code> in an Android shell and it works great. I tried to change the init.rc file. I added the above code in init.rc and I replaced it with the original file, through these commands: <code> adb push init.rc sdcard adb shell adb su mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 / adb cp sdcard/init.rc / </code> The file is replaced successfully, but when I reboot my phone and try to connect through: <code> adb connect <IP>:5555 </code> the connection is not being established. Any ideas? (PS. I don't want to use the remoteADB application and a shell command like <code> am start -n ... </code> )

The reason it does not work properly is this: The <code> init.rc </code> script resides in within the RAMDisk attached to the boot image. Hence the <code> init.rc </code> script that was edited and pushed across is now overwritten by the boot image's own script upon reboot - effectively changes are lost! You need to extract the boot image, using every boot image has the kernel and the RAMDisk. The tools available to do this can be found here . Extracting When invoking the script <code> split_bootimg.pl </code> on a boot image it will recreate the following: boot.kernel boot.ramdisk.gz The two files are obviously self-explanatory. To extract the ramdisk, create a directory called RAMDisk and from that directory, invoke this: <code> gzip -dc | cpio -i </code> , to recreate the directory structure that is used in the RAMDisk which gets flipped over to the live file-system upon boot. In there, the file that is of pertinent information is <code> init.rc </code> . Now that can be modified to your heart's content. Putting it back together Go back up a directory level, and issue this - <code> mkbootfs ***RAMDisk*** | gzip > my_custom_ramdisk.gz </code> . Then, to "attach" the original kernel to the boot image, issue the following: <code> mkbootimg -base 0x.... -kernel boot.kernel -ramdisk my_custom_ramdisk.gz -o my_custom_boot.img </code> . At this point now, a boot image has been constructed, then that boot image will now have to be flashed via <code> fastboot flash boot my_custom_boot.img </code> . TL;DR Changes are lost upon re-boot because the script is not properly edited which required extracting the boot image and modifying it and re-packing it. Once re-packed and then the boot image is re-flashed, the changes will be permanent. This is done every-time the changes are needed.

Where are the official release notes for Cyanogenmod, in particular the 9.1 release? I wasn't able to find them.
|
Did you check with the official changelog site ? Or the XDA thread on 9.1 ? The latter mentions http://cm-kang.appspot.com/anzu/ics for the changelog. And then there's this page where you even can filter changes by devices (probably the best source to check). If you need more details: All that from page 1 of a simple Google search for cyanogenmod changelog "9.1" (<- hint! ;) ) To the first (and explicit) question: If there were any new features? That probably very much depends on your device. So using the last changelog source I mentioned, filtering by the device you want to know this about, you will be able to answer your question. As I don't know your device, I can't ;)

On my HTC MyTouch 4G (Android 2.3.4), twice now the diagnosis for odd failures was to take the battery out, wait a minute, and replace it. (The first failure was loss of network; the second was web sites only partially working, e.g. I could read SE sites but not log in.) Both times popping the battery fixed it, and my provider told me I should do this every couple months as "preventative maintenance". This violates my mental model. So, clearly, either my mental model is wrong or HTC and the folks at T-Mobile are having fun with me. I'm going to start by assuming it's the former. I power the phone down at least once a week. I think of this as being like rebooting a laptop computer; when it's powered down I don't expect the battery to be retaining any state. But if that's true, why does performance degrade over time? What is my phone doing with its battery during these times? Does periodically powering down do anything useful, like kill long-running processes? I tried Google and reviwed the "battery" questions here before asking.
|
It's not the battery retaining state, it's the phone circuitry retaining state. Even when you use a "power off" command and your phone looks powered off some of the circuits will still be connected to the battery so that the phone can be turned on by just pressing the button. So there will be some circuitry powered on even after the phone was "powered off". This is likely a bug in the circuitry. This actually happens to devices - you sometimes need to "power cycle" them by unplugging them from the power source and then plugging them back. In case of a mobile phone that requires removing and then installing the battery.

I just moved to Android from iOS. My new droid is Sony Ericsson Xperia Neo V which came with a 2GB SD card. This card is almost full so I want to get a bigger and faster SD card. I have installed many apps on this SD card so I'm wondering how I can move all the content of the old card to the new one when I finally purchase it. How do I do this?
|
As the solution described by yrajabi basically works, it might miss some data -- e.g. if you have moved some apps to SD card using App2SD , you might miss them afterwards. So a much safer approach is: shut down your device take out the SDCard put the SDCard into a card reader, and attach this card reader to your PC make sure all files are visible in your "copy GUI" (which ever you use) copy all files and directories, including hidden ones, into an empty folder on your computer safely unmount the card, and replace it by the new one same way, copy all data (including hidden files/directories) to the new card safely unmount that card, and place it back into your device power up the device, you are done This way you can make sure no files/directories have been hidden from you.

With a touch screen keyboard, having passwords I am entering displayed hidden is more trouble than it's worth to me. Few applications like KeePassDroid allow you to disable this feature. Is there any way to disable this feature globally? Solutions that require root are perfectly fine.

Which version of Android and which phone are we talking about :D ? On my HTC Desire running Android 4.0.4, in Settings -> Security -> Passwords, there is an option saying "Make passwords visible". I don't use this but it might help you.

I just got for myself this new phone with so many useless bloatware. I just want to root this phone and freeze or uninstall them as they are slowing my device down (even without opening any app, all I have out of my 350mb + RAM is an average of 50mb). Can someone please help me out with a noob step by step guide? Thanks in advance. SPECS: Sony Ericsson Xperia Neo V (MT11i) Android 2.3.4 Bootloader locked (but can be unlocked)

According to stackexchange-url ("How to install ClockworkMOD Recovery on Sony Xperia Neo V") this should be possible using UnlockRoot (download), which requires a Windows (XP/VISTA/7) computer. The process is described at How To Root Android Devices Using Unlock Root Tool, basically as follows: You should have a backup of your data (for safety reasons) Your device should be fully charged USB drivers for the device should be installed on PC USB Debugging must be turned on in the device Connect the device to PC using USB cable Run the downloaded tool, and Click on “Unlock Root”, That’s it. Another guide available is Learn How To Root the Sony Ericsson Xperia Neo V -- in case you are not satisfied with the described method ;) Good luck!

I have a Droid RAZR MAXX, and there are a few shortcuts to web pages on the screen. They have been there since before the phone got ICS. Under GB one could long tap the screen, add a shortcut, and choose a web site rather than an app. This created a shortcut with the name of the site, and the icon looked like a screen capture of the URL that the shortcut targets (like the chrome new tab page). However in ICS I can't see way to do it, I can add a bookmark to the home screen through the browser, but the icon is different. I tried adding a bookmark through each browser, chrome, default, firefox, opera, dolphin. None of them produce this icon. Anyone know how to do it? Or is this something that Moto threw in to the software, but didn't keep in ICS? (Though in that case why do the old icons still work?).
|
Can't see how to get an individual bookmark with a thumbnail screenshot of the webpage, but there are a couple of similar things you can do with the default browser in ICS. In the screenshot above the top row are bookmarks added to the home screen by going into the browser, opening the bookmarks list, long pressing on a bookmark and selecting "Add to Home Screen". These appear to be the using the site's "Favicon". The next two rows are the "3x2 Bookmarks" widget, that just lists the contents of my browser's bookmarks folder. Add that by opening your apps list, selecting the Widgets tab at the top and then long pressing to drag the "3x2 Bookmarks" widget to a home screen. It then gives you a chance to pick a folder in your Bookmarks to show (you could create a new folder in bookmarks beforehand and fill that folder with only web pages that you want to show on your home screen).

I've found this comment: stackexchange-url ("Any reason not to allow automatic updating for an app?") - is that safety feature documented anywhere ? I'm about to turn on automatic updates but I don't feel comfortable doing that without a firm proof that it won't compromise security.
|
It's not documented somewhere. But only updates that don't change the permissions are done automatically. If there is a change, the update will have to be done manually. But of course there is no gurantee that this will always work this way, because of bugs or design changes. If you are paranoid, turn the feature off. (But then, how could you trust Android that the permissions that are shown to you are enforced?)

Naive question, but when I check the specs of a phone, one website says phone has feature X, the other says it does not have this feature. Here I am interested in the ambient light sensor. What does it look like, and where it is usually placed? For example , GSM Arena review says the HTC One V has an ambient light sensor: "Above the display is the earpiece alongside some hidden proximity and ambient light sensors." The photo: For comparison the text says I should see the proximity sensor too. On my Galaxy Ace 2 it looks like 2 mini cameras, it is hard to miss, and on that picture I don't see anything like that. Of course maybe HTC hid that all so well. Anyway, I would like to know what I am looking for, thus the question -- What does the ambient light sensor look like?
|
It's hard to see it in normal light, you may need to take your phone under a very bright light to be able to see it (e.g bulb light or straight sunlight). It looks like a darker and smaller front face camera. If GSMarena has said that it has light sensors, then in my experience, its near 100% correct. BTW, if you can't bring light sensor to work, there is a free software called Lux Auto Brightness which does the job very nice and has many options.

I just got my Nexus 7 tablet and I was trying to load some music/videos to it. I have about 10 gigs worth of .mp3 files with no DRM in my computer. Since this is Android, I figured I would not be subject to the pain that is iTunes and I would simply be able to drag the music into a "Music" folder if I plugged in the tablet to my computer. Sure enough, I saw a folder named "Music" and tried dragging a couple of files to it. When I go to my Nexus, however, I don't see the files. I started reading up on this and it seems that the way to do things on Android is to use the Google Music Manager which would then put my songs in "the cloud" and make them playable from any device. That's all nice and everything, but is there any way to simply put a couple songs into my device locally without any of that funny business? TL;DR: I don't want to use Music Manager, how do I locally upload a song/video to my Nexus 7?

Android uses a so-called Media Scanner to index your media files (this also applies to your images and videos). This Media Scanner ships with the system, and fires automatically on certain system events -- such as after boot, or when you insert your SD-Card. It does, however, not react on a simple "file-drop" via network. For such cases, it might need a little help to get to know it has to act: Rescan Media Rescan SD Card! Are two free example apps from the playstore which do exactly that: trigger the Media Scanner . Once the Media Scanner has indexed your new files, they will immediately show up in the corresponding apps such as the gallery (for images/videos) or your music player.

I want to double check that my HTC One XL is evita model. I am almost sure I saw it in a menu somewhere but I cannot find it anymore. Could somebody guide me where I can find such info?
|
According to the Wikipedia article , all the HTC One XL devices fall under the Evita model. Evita is just the code name for the device. Just about every device is initially manufactured with a "codename". This is more just like an internal name for the device. This could be because they have not decided on a "public brand" for the device yet, or just because they want to call it something else internally. Sometimes the codename resides in the model name in the Settings -> About Phone. But if you have <code> adb </code> access to your device, you can do something like: <code> > adb shell $ getprop </code> this will dump out all the properties that are configured during the boot process. one of them, probably something like <code> ro.product.device </code> will contain the value <code> evita </code> .

The General Question : Is it possible to install custom kernels on a Rooted Stock ROM? The Example : I have a Nexus 7 which I have rooted running 4.1.1 (Jelly Bean JRO03D) would it be possible to just flash a custom kernel, say this one http://forum.xda-developers.com/showthread.php?t=1831780 , on my stock ROM using Clockwork Recovery? Sorry if this is obvious, but I've only really done it on custom roms, and I couldn't find a definite answer on the interwebs
|
Yes, it is possible to install custom kernels on stock roms. The kernel developer will usually say which roms (or types of roms) the kernel supports. If you are not sure you can try reading the kernel thread, and there will always be poeple saying things like "working great on [firmware version here]". This way you can also make sure that it will work ok on your version of the stock rom. As for your example, yes you can flash this on your stock rom: xda-developers
